In this experimental study, was conducted to investigate the durability properties of Hybrid fibre reinforced concrete (HFRC) containing Copper slag with various percentages of fibers like Steel fiber and Polypropylene fiber is evaluated. The usage of steel fibers in concrete converts its nature from brittle to ductile. Cracks plays an important role in construction as they change concrete structure into a high risk of corrosion and it is important to reduce the crack width and this can be achieved by adding polypropylene fibers to concrete. The concrete mixes were designed for five different mix proportions such as 10%, 20%, 30%, 40% and 50% of copper slag as replacement of fine aggregate with the small percentage of fibers as constant. The main objective of this study to determine the durability properties such as acid attack and sulphate attack test in the Hybrid fibre reinforced concrete. Test results shows that the durability properties of concrete have improved by using copper slag as a partial replacement of sand upto 40%. Hence, the durability properties of these mixes were found and then comparing those results with the conventional concrete. By the usage of optimum usage of copper slag durability characteristics will be evaluated.
